NOTE: CO2 gas is extremely compressible, and therefore expandable, relative to other gases. CO2 gas is typically stored under very high pressure. A needle or metering valve is not designed to drop the pressure from your CO2 regulator down to a working pressure. This is the job of the CO2 regulator itself. The needle valve`s sole purpose is to regulate CO2 flow precisely. Equipping your existing CO2 regulator with a needle or metering valve may not provide you with adequate fine-adjustment for a calcium reactor. These valves are fragile and be easily damaged if not hooked up to the proper regulator. Our Deluxe CO2 Systems already include a Precision Needle Valve which enable as low 6 bubbles / minute (NOT second).

**Variations of this product can be found in many online stores. The version we carry is of the highest quality. Although this item is eligible for price matching under our Low Price Guarantee, please be certain the product you want to price match is the same make and model.

Needle Valve For CO2 Regulator

Great needle valve

by
AMIT BAPAT

Excellent!

Comments:its super compact and ease to use. I got it to attach to my redsea regulator. Needed some tape around the threading to make an airtight connection. Other than that the valve has been working great.
I can accurately control the flow. Currently using it on a 8.5 gal tank so need a slower bubble rate~1 bubble/ sec. Will definitely buy it again, if needed.

Still super sensitive

Comments:I was hoping this would be VERY granular for adjustment, but in the end it's still extremely sensitive. Trying to adjust from 40 bubbles a minute to 30 is quite difficult, and anything more granular than a 10 bbl/min adjustment seems unlikely.
I'm still glad I got it as I do have more control than I previously did, but in general it wasn't exactly what I had hoped for.

Great Replacement!!

Comments:Seemed a bit too sensitive at first, but once I had it locked at the proper adjustment, the volume hasn't deviated at all. Compared to the factory needle on my regulator, this unit is a treasure!!
